Tower Crane TC4808 FAQ:

1.What is tower crane?

Tower crane is a modern form of balance crane that consist of the same basic parts Fixed to the ground on a concrete foundation (and sometimes attached to the sides of structures as well), tower cranes often give the best combination of height and lifting capacity and are used in the construction site.

2. What is the meaning of the tower crane’s code?

Take Tower Crane TC4808  for example, the first two letters “TC” means Tower Crane, “48” means jib length is 48 meter, and the last two letter “08” means the tip load is :0.8 ton.

3. What is the principal to quote the right tower crane to the client?

First, we need to know clients’ requirements,for example, max lifting capacity, height, tip load and jib length.. Second, we need to know what the foundation requirement from the client is and Third if there are special needs. CNBM could suggest proposal according to clear data provided by the clients.

Q:Tower crane 10-5-20 is 6T, and 10-5-21 is 8T. What do you mean by tons?
6T/8T refers to the maximum lifting capacity of a tower crane. It doesn't matter what 10-5-20 has to do with it. Maybe your list of numbers is serial number.
Q:Emergency treatment of interrupted electricity during lifting of tower crane
When the power supply fails, you should first remove the things that are stuck in the gear!
Q:What is the scrap standard of tower crane hook?
The hook shall be scrapped at any time in the following circumstances:Crackle;The wear of the dangerous section is 10% of the original size;The opening ratio is increased by 10% than the original size;The twist of the hook is over 10 degrees;The dangerous section of the hook or the neck of the hook produces plastic deformation;The hook thread is corroded;When the hook bushing is worn at 50% of the original size, the bushing shall be replaced;The mandrel shall be replaced when the hook mandrel is worn at 5% of the original size.
Q:What does "automatic tower crane" mean less than 100 tons per metre?
The problem is a bit ambiguous, 100 tons of rice is the lifting moment.
Q:What kind of bodies are tower cranes made of?
Two. The metal structure of tower craneThe metal structure of tower crane is mainly composed of underframe, tower body, jacket, upper and lower support, suspension arm, balance arm, tower top and other main components.Metal structure is the framework of tower crane, which bears the deadweight of crane and all kinds of external loads during operation.Three. Power unit and control systemThe power unit is the power source of the crane, and the power source of the tower crane is an electric motor with an external power supply.The control system includes controls and safety devices. Control device for tower crane is composed of a linkage control console, distribution box, resistor box components, the safety device is mainly composed of height limiter, amplitude limiter, lifting weight limiter, moment limiter, slewing limiter etc..Through the control system, the movement characteristic of the crane can be changed, so as to realize the starting, speed regulation, modification, braking and stopping of each mechanism, so as to achieve various actions required by the crane operation.
Q:How high the tower crane needs to be installed with the wall pole. How is it stipulated in the national standard?
Beyond the maximum independent height of the tower crane design, a wall attaching rod shall be installed
Q:How many meters does the tower crane installation height require expert proof?
The installation, disassembly and jacking of tower cranes must be carried out by experts
Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
1. Tower crane consists of three parts: metal structure, working mechanism and electrical system. The three main technical parameters are lifting moment, lifting weight and working speed. Lifting moment refers to the boom as the basic arm length maximum amplitude corresponding to the rated lifting weight of product, product or maximum weight with the corresponding inflection point.
Q:What are the characteristics of a tower crane?
Classification and characteristics of tower cranesAccording to whether or not there is a walking mechanism, it can be divided into movable tower crane and fixed crane.Mobile tower cranes can be divided into four types: track type, tyre type, automobile type and caterpillar type according to the difference of walking device.The track type tower crane tower body is fixed on the walking underframe, and can be operated on the specially designed track. The utility model has good stability, can walk with load, and has high work efficiency, so the utility model is widely used in construction and installation engineering.The wheel type, the automobile type and the crawler type tower crane have no track device, and they are easy to move, but can not walk with load and have poor stability.The fixed tower crane can be divided into two types: the attached self lifting type and the internal climbing type according to the different installed positions:The attached tower crane can rise as the building rises. It can be applied to the high-rise building. The structure of the crane can only bear the horizontal load from the crane, but it is easy to use, but it occupies more steel structure;The internal climbing crane in the interior of the building (elevator, staircase), up through a set of system and improve the lifting bracket, is complicated, but occupy steel less, do not need to be installed, all the weight and load by building bear.
Q:What are the luffing, slewing, and walking points of a tower crane?
The luffing of a tower crane is the forearm of a crane;Slewing means the steering mechanism of a crane;Walking means the walking trolley on the luffing range of a crane
